Целью изобретени   вл етс  повышение степени чистоты получаемого водорода.The aim of the invention is to increase the purity of the hydrogen produced.

Пример. Водород получают в скл нках Тип1енко, соединенных концами с двум  сборниками водорода, работающими по принципу вытеснени  затворной жидкости в сообщающиес  сосу. ды. Все емкости соединены одна с другой резиновыми трубками с зажимами.Example. Hydrogen is obtained in Type Ienko bottles connected to the ends with two collectors of hydrogen, operating according to the principle of displacing the barrier fluid into a communicating vessel. dy All tanks are connected to each other with rubber tubes with clips.

В качестве затворной жидкости берут насыщенный раствор хлористого натри , подкисленный серной кислотой (300 г, 10 мл серной кислоты на 1 л дистиллированной воды).A saturated solution of sodium chloride acidified with sulfuric acid (300 g, 10 ml of sulfuric acid per 1 liter of distilled water) is taken as a barrier fluid.

В качестве источника водорода используют дистиллированную воду, а также воду, имитирующую черноморскую воду на глубине 300 м и содержащуюDistilled water is used as a source of hydrogen, as well as water imitating Black Sea water at a depth of 300 m and containing

По данным химического анализа полученный водород содержит 0,03 мг/л углекислого газа.A compressed tablet of a hydro-reactant composition weighing 2.0 g, consisting of a homogeneous mixture of fine powders of aluminum and lithium hydride in the ratio of 84:16, is attached to a cork of a Tishchenko bottle with a thin strip of insulating tape. 10 ml of distilled water is poured into the flask, closed with a cork and placed in the working position (on the cork), simultaneously blocking one of the collections of hydrogen with a clip. The hydrogen released during the reaction is collected in another collection. According to chemical analysis, the resulting hydrogen contains 0.03 mg / l carbon dioxide.
